[ECOS] Problem with a revived project in building redboot for the SH and being used by the Sega Dreamcast

["Gregg Levine" <gregg dot drwho8 at gmail dot com>]

Helllo!
To be honest I am quite sure that this has been covered before.
Certainly it is new to me today. I have revived a project concerning
the port of eCos and Redboot to to the Sega DreamCast and encountered
a problem. The reasonably relevant portions of the output are below my
signature lines.
